TutorMobile

TutorMobile was our core product at TutorABC/iTutorGroup with over 20,000 Monthly Active Users. It was a mobile app designed for the iPad and iPhone which consisted of all the functionality of taking courses online: registering for courses, attending courses with streaming video, two-way voice and live messaging, reviewing courses – including viewing recorded videos of the course, submitting homework, and leaving reviews for classmates and instructors.
